Sales of the PSP in the United States have rocketed 300% in the 3 days that followed the launch of the PSP Go - the smaller, lighter, more download-y, little brother of the original PSP-3000. Game downloads also climbed 200% in the same time period.

Sony's corporate communications director Patrick Seybold told Gamasutra: "The launch of PSPgo has generated strong consumer interest in the overall PSP platform and the PlayStation Network's digital content offering".

"With several blockbuster games launching digitally and on UMD in the coming weeks - from LittleBigPlanet to Assassin's Creed Bloodlines - we expect this momentum to continue and look forward to a strong holiday season for both the PSPgo and PSP-3000", he added.

Over on this side of the Atlantic, a price war erupted for the new console, with the cost dropping £25 almost immediately. The console is available now for around £200, depending on where you pick it up from.
